Hey,
you can use this site http://ripplepaperwallet.com (offline) or this https://ihomp.github.io/ripply-paper-wallet/coldwallet-SHA1-cdfbe3260927b6073180a1099f02ef99ce0495e8.html to create a paper wallet.
(Also here, the 20 XRP will be locked to the adress)
The current balance I check with bithomp: https://bithomp.com/explorer/
It is quite difficult to withdraw from a xrp paper wallet - one solution is one of the light ripple clients ... never tried to withdraw so far :-)
Cheers
Thanks!
